Edit: (June 30, 2010) The tower is almost complete, possibly by tomorrow. When it's finished, I'll upload the new version for you guys. It's being thoroughly tested, so there shouldn't be any bugs.
I'll go ahead and tell you now that floor 26 and up are going to be a nightmare. The last few sets don't mess around and some scenarios in them will be harder than the final area. On that thought, development will start on it shortly. :)
Edit: (June 27, 2010) After completing floor 15 of the tower, trying to go to floor 16 from the reward room will give an error. You can click ignore though and it will still record that you completed that set.
Released an updated version. This is quite a large one sorta. Fixes up a few things with the newest area. Probably stuff that no one saw hopefully. There are 5 more floors available in the tower. On the subject of the tower, the next update will have it completed. There's a new extra area which branches off the Veiled Detritus, should bring lots of new deaths. There are also a few new hidden maps, some of which are fairly easy to find, some are there to taunt early players. Check your map to see which ones have new areas to find.
The Mario [?] blocks are fixed and work better than they did when they initially worked. There are breakable blocks there now too, excuse the lack of sound when they are hit for now.
Oh, one more thing. If you completed the latest demo, check to message in the Data Center for what you have to do next, it now accurately shows what to do. The end cutscene dialogue changed very slightly to reflect on what it says to do next. (It basically says to go to your Sky Base.)
I think that's it for this announcement. I'll update this when the tower is done... unless one of you find a nasty crash bug, then you get more floors if anymore are playable when it's fixed and reuploaded.
